Use this free online mandolin tuner to tune your mandolin. This is for the standard GDAE mandolin tuning. For other methods on how to tune your mandolin go to our Mandolin Tuning Methods page. Mandolins have strings that are in pairs, which are tuned to exactly the same note. These pairs of strings create a cool chorus-like effect, very similar to the sound of the 12 string guitar.
How to use this tuner: Click on the note for the string you want to tune and then turn the tuning pegs on your mandolin to match it up with the note that is being played. For best results adjust the volume on your computer until it has the same volume as your mandolin.
